BS 476-7 Surface Spread Flame Tester for Measuring the Flame Extension of The Wall
Product introductionBS 476 Part 7 specifies a method of test for measuring the lateral spread of flame along the surface of the specimen of a product orientated in the vertical position under opposed flow conditions, and a classification system based on the rate and extent of the spread of flame. It provides data suitable for comparing the end-use performances of essentially flat materials, composites or assemblies, which are used primarily as the exposed surfaces of walls and ceilings. Product parameters1. The area of the radiant panel is 850mm X 850mm, and the
structural support frame is strengthened; Features and Application1. This Apparatus consists of a radiation panel mounted vertically
in a surround and supported on a framework. Product Details of the Surface Spread Flame TesterThe surface flame propagation test device is a BS 6853 series
high-speed steel flame retardant tester, which is suitable for
British building materials and high-speed steel flame retardant
test standards. The standard is BS 476-7. The test method is used
to determine the lateral extension of the sample surface and based
on the speed. And the extension length determines the burning
level. BS 476-7 is primarily used to measure the flame extension of
exposed surfaces on walls and ceilings. Standard:BS:BS 476-7 Installation requirements Electrical: 230 volts Nominal 10 Amps Surface Spread Flame Tester.pdf What is spread of flame test? Flame spread tests aim at measuring the tendency of a flame to propagate over a substrate and directly correlate to surface flame propagation in a real fire scenario. |
